Soux Chief 653-B Hydra ester Water Hammer Arrester for Piping Systems

This water hammer worked perfectly. It stopped the banging on each of my 5 sprinkler zones.

Works great. I put it just upstream off my sprinkler valve manifold. Used to have a pretty loud banging from the pipes when the sprinklers went on and off, now there is no noise at all! $22 and some elbow grease, yesss!

Works exactly as described. I installed these using a combination of fittings on the back of our washing machine and it completely eliminated the water hammering from our Kenmore washer. The water lines don't even so much as move anymore.

I had a the banging of the pipes every time my irrigation system would turn on or off. I had serveral plumbers come by with no resolution. So you Plumbers, take heed and have these in your arsenal for knock repair. It works if you place it near the offending device. In my case I easily installed it on the irrigation valve myself and the banging went away. I did have to purchase a PVC cutting tool from my local box store along with a piece of PVC and sealant. But once done, I resolved a problem I had since I purchased the house 4 years ago. Only problem, I have to replace annually it appears due to hard water in desert. But it easy to install now that I have it set up and it’s not expensive..

Installed it on my washing machine hot and cold and on my dishwasher. I now forget sometimes I am washing as I got so use to the pipe sounds to tell me the washer is done. Banging of the water pipes is completely gone. Strong build , it seems durable as there was no metal flaking or compression while tightening it to the dishwasher line or washing machine line. Had no leaking.

After o stalling a pressure regulator valve, started getting loud pressure oscillations when the flow went up quickly. This thing solved the problem. Many people use them to eliminate water hammer caused by a washing machine. Be aware, this thing has parts that will wear out. I expect to replace mine in about 10 years.

This is what I needed. I initially tried one meant for a washing machine on my outside faucet timer. It did not work. I upgraded to this and no noise at all. As others have said, you will need an adapter because the arrestor is pipe threaded.

Like others have said, the threads will likely be damaged. They really should have a plastic cover over them during manufacturing to protect them from damage as they are likely tossed in a bin before being boxed up. As it was, it leaked the first time, so I had to take it apart and file on the threads a bit to smooth them out.As for the hammering, it has helped, but not eliminated it. I still get one or two hits before it kicks in, but it is better than before.Other issue is that it says one day shipping, but it was two days for me, which seems to be an issue with a lot of Prime products any more. Tell me up front it will be two (or three) rather than suckering me into ordering it because you claim it will be next day.
